Therefore<br />there has been a great deal of interest and research in order to understand the effect of processing<br />parameters on the functional properties of the isolate. The major purpose of this research is to study<br />the foamability of the different proteins - starch nano-particle system. The results from experiments<br />revealed that the foam properties can vary significantly for certain protein solutions; however, the<br />interfacial properties seem to be constant and the most important results from the experiments are<br />A) in starches samples, adding protein had no significant effect on viscosity, consequently, there was<br />no drainage limitation B) for starches sample surface tension is not limiting factor C) At same starch<br />concentration Egg White protein (EWP) foams had a much higher drainage half-life time compared<br />with pea protein (PPI) foams. The affected properties on foam stability, such as viscosity, surface<br />tension and pH were compared to discover the best solution for foam stability.Surface Tension,EWP,PPI,Nano-Particle,Overrunhttp://www.jnanoanalysis.net/article_539939.htmlhttp://www.jnanoanalysis.net/article_539939_fa7e027081f1cb3c1554435f443eb75f.pdfPharmaceutical Sciences Branch, Islamic Azad University (IAUPS)Journal of Nanoanalysis2383-03444420171201Electronic Behavior of Doped Graphene Nanoribbon Device: NEGF+DFT272279ENSadeghAfshariSchool of Chemistry, Damghan University, Damghan, Irans.afshari@du.ac.irJaberJahanbin SardroodiMolecular Simulation Lab., Azarbaijan Shahid Madani University, Tabriz, Iranjsardrodi@azaruniv.eduHakimehMohammadpourDepartment of Physics, Azarbaijan Shahid Madani University, Tabriz, Iran10.22034/jna.2017.539940Quantum transport properties of pure and functioned infinite lead-connection region-lead system<br />based on the zigzag graphene nanoribbon (2-zGNR) have been investigated. In this work the effect<br />of the doping functionalization on the quantum transport of the 2-zGNR has been computationally<br />studied. Also, the effect of the imposed gate voltages (-3.0, 0.0 and +3.0 V) and bias voltages 0.0 to<br />2.0 V have been studied. The results were presented as the current versus the bias voltage (I-Vb)<br />curves with unique properties for per studied systems, showing one or two negative differential<br />resistances (NDR). The NDR region was discussed and interpreted in the terms of the transmission<br />spectrum and its integral inside of the corresponding bias window. Also, the partial atomic charge<br />distribution in the center part of the system’s scattering region containing carbon atoms at the left<br />and right sides of substituted atoms which are connected to substituted atoms has been investigated<br />for different bias voltages.graphene nanoribbon,partial atomic charge,NEGF,NDR,dopinghttp://www.jnanoanalysis.net/article_539940.htmlhttp://www.jnanoanalysis.net/article_539940_6da182633f6c20916b7e9ced442e04d6.pdfPharmaceutical Sciences Branch, Islamic Azad University (IAUPS)Journal of Nanoanalysis2383-03444420171201Synthesize and Characterization of Hollow and Core/Shell Based on CeO2 as a Alcohol Sensor280289ENZahraRasouliDepartment of Chemistry, Science and Research Branch, Islamic Azad University, Tehran, IranMohammadYousefiDepartment of Chemistry, Science and Research Branch, Islamic Azad University, Tehran, Iranmyousefi50@hotmail.comSusanSamadiDepartment of Chemistry, College of Basic Science, Yadegar-e-Imam Khomeini (RAH) Shahr-e-Rey Branch, Islamic

In this respect, using natural<br />resources,especially plant extract has attracted lots of attention; plant extract is a promising<br />alternative to traditional and chemical techniques. The plant Mucuna pruriens L. contains high<br />concentration of L-dopa in the seeds; it has been used as a nerve tonic for nervous system<br />disorders including Parkinson’s disease. In this work, a rapid and efficient synthesis of stable<br />magnesium oxide nanoparticles (MgO NPs) using aqueous extract of Mucuna pruriens seeds<br />were reported. The biologically synthesized MgO NPs were characterized by UV–Visible and<br />Fourier transform infrared (FTIR) spectroscopy as well as X-ray diffraction (XRD), scanning and<br />transmission electron microscopy (SEM and TEM). The potential of MgO nanoparticles in the<br />degeneration of methyl orange (MO) and methylene blue (MB) dyes were assessed in different<br />conditions. The results of these investigations showed that the synthesized MgO NPs have<br />a good catalytic activity in the removal of both dyes.
